I have a CI job which runs 'setup -q -P python3,python3-lxml'. It's nice if
that gets me something where "python3 -c 'import lxml'" works, and doesn't
require changing every time the default python version is updated.
Currently python3 is a meta-package whose main purpose is to require the
default python version (currently python38). Marco, couldn't you just make
python3-foo a meta-package that requires the corresponding python*-foo
(currently python38-foo)?
the issue is that Cygport creates the "obsolete" python3-foo
that is replaced by python36-foo automatically.
we should change cygport to use python38 instead

$ cat python3-lxml/python3-lxml-4.6.2-1.hint

one, to be installed instead."

As long as you have to patch cygport anyway, maybe it would be better to have
cygport create an empty (but not obsolete) package. I think users might find it
confusing that they have to install an obsolete package to get what they want.
Also, obsolete packages are normally hidden in the setup UI.
Hidden generic/virtual package selections in Debian apt/-get and other package
managers are annoying as users (I!) don't know how to do anything when they find
out about them e.g.
$ apt show exim
Package: exim
State: not a real package (virtual)
N: Can't select candidate version from package exim as it has no
candidate
N: Can't select versions from package 'exim' as it is purely virtual
N: No packages found
Suggest adding a category like ~Generic or ~Virtual to sort out of the way but
be selectable if you search for Python, Perl, Ruby, etc.
I have been unable to find any definitive category list where that might be
checked, except in cygwin-apps/calm/genini, and I believe that is not being used
any more, as it is missing Debug but includes obsolete Mingw.
